Ancient solution phenomena in the Madison Limestone (Mississippian) of north-central Wyoming
A karst topography was developed on the Madison Limestone of north-central Wyoming during the middle Meramecian early Chesterian time interval. Ancient karst features include enlarged joints, sinkholes, caves, and solution breccias that resulted from leaching of evaporitic beds in the upper 400 ft of the Madison bedrock. These features are predominantly phreatic rather than vadose. Most of the open spaces are fdled by sand and residual products reworked by the early Amsden sea, which transgressed the area during the Chesterian.

Revision of some of Girty's invertebrate fossils from the Fayetteville Shale (Mississippian) of Arkansas and Oklahoma
J.n 1910, G. H. Girty published a paper on the fauna of the Fayetteville Shale of northern Arkansas and northeastern Oklahoma in which he described 110 new taxa of fossil invertebrates. He did not, however, designate any type specimens or divulge the localities at which •the fossils were collected, nor did he illustrate the species. The present study is designed to fill the gaps in information on some of these species and to bring them as far as possible up to date and in line with the modern scheme of classification. This report deals with the corals, pelecypods, _gastropods, trilobites, and ostracodes. It does not include the brachiopods and bryozoans. The study has been performed by specialists of the U.S. Geological Survey who are contributing separate parts to the volume.
